After being selected Boating School Hall Monitor (after everyone else in class has been, sometimes twice), SpongeBob reads out a very long speech, and winds up wasting the entire day. Out of sympathy, Mrs. Puff allows SpongeBob to at least wear his cap and belt until the next day, though she suddenly has misgivings as she watches him go. SpongeBob immediately goes above and beyond the call of duty, first trying to guide traffic stuck at an out-of-order traffic light (and causing a massive pile-up), and then inadvertently igniting the rumor of Bikini Bottom's Open-Window Maniac. Then, SpongeBob finds Patrick littering his strawberry ice cream, and labels him as a criminal. When a front page newspaper headline alerts SpongeBob about the maniac causing trouble around town, he lets Patrick turn over a new leaf as a deputy. They end up getting ice cream twice (Patrick's idea of a scandal), but then SpongeBob and Patrick try and corner the maniac by splitting up and using walkie-talkies. Two policemen ask Patrick if he has seen the maniac: they show him a bad police sketch of SpongeBob. Darkness falls upon the town, quite literally, and Patrick becomes frightened. SpongeBob eventually meets up with Patrick again, but only via the walkie-talkie. Patrick spots the maniac from a distance, and reports his every move to SpongeBob, who of course believes the maniac is right on his tail. Shortly enough, SpongeBob realizes he himself is the maniac. The police are about to arrest SpongeBob, but Mrs. Puff tells the officers that he was her responsibility. Mrs. Puff must teach the next day's class via closed-circuit TV, from her jail cell.

How can SpongeBob think of a hall-monitor speech at least 6 hours long?

At first, Mrs. Puff was holding the hat and belt, but after SpongeBob’s boring speech, he has the hat and belt.

When the police drive up to Patrick, both police's eyelids are green. But when they talk to him, the orange police's eyelids are orange.

The sky can't fall for it to be dark. Earth's rotation causes day and night, not a falling sky, but day always turn to night.

The song in the background when SpongeBob is giving his speech is the Pomp and Circumstance graduation theme.

This is the first time a character got sent to jail.

This is the first appearance of downtown Bikini Bottom.

When Spongebob was hall monitor he was braking tons of laws like breaking in those two fishes house.

It would seem that SpongeBob has never been hall moniter. However, when he finishes his speech he says to Mrs. Puff, "I overdid the speech again, didn't I?" It is possible that SpongeBob has been chosen multiple times, but Mrs. Puff never marked his name. This would mean that every time, he makes his speech too long.

When Mrs. Puff is randomly yelling names in the beginning of the episode, she yells the name "Clayton", which is the name of Stephen Hillenburg's son.
